GATE.

SPECIFICATION forming part of Letters Patent No. 262,087, dated August1, 1882.

Application filed January 14, 1882. (N0 model.)

To all whom it may concern Be it knownthat I. JAMES WILLIAM MOR- RIsoN,of Logansport, in the county of Cass and State of Indiana, have inventeda new and useful Improvement in Gates, of which the following is afull,clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure 1 is a plan view of my improvement. Fig. 2 is a side elevation ofthe same, partly in section, through the line a; m, Fig. 1. Fig. 3 is anunder side View of the cam-wheels, partly in section, through the line yy, Fig. 2.

This invention relates to the class of gates that are arranged to beopened and closed from a distance at either side of the gates, and hasfor its object to facilitate the opening and closing of such gates.

The invention consists in the combination,

with the gate and its latch and latch-spring,

operating-levers and their wires, of a. latchlever, a cam-wheel and itsspring, and a pulley and its chains, whereby the cam-wheel can be turnedto open and close the gate, as will be hereinafter fully described.

A represents an ordinary gate. Bis the rear or hinge post. 0 is thefront latch-post, and D is the side latch-post.

To the upper end of the rear end barot' the gateA is attached, or uponit is formed, a spindle, E, upon which is placed a cap-wheel, F.

Around the spindle E is coiled a spring, G, one end of which is attachedto the end bar of the gate A, and its other end is connected with thecap-wheel F by a staple or other suitable means. The spring G is soarranged as to bring the cap-wheel F back to its normal position afterbeing turned in either direction.

Upon the under side of the forward part of the cap-wheel F is formed acam-recess, H, to receive the upper end of a lever, I, or a smallfriction-roller, L, placed upon the upper end of the said lever I. Thelever I is pivoted at its middle part, at i, to a bar of the gate A, andits lower end is pivoted to the latch J, which slides in mortises in theend bars of the gate A, and is held forward by a spiral spring, K,placed upon the rear part of the said latch J, with its rear end restingagainst the rear end bar of the gate, and its forward end restingagainst a shoulder formed upon the said latch.

To the upper side of the cam-wheel F is attached a pulley, M, to theopposite sides of which are attached the middle parts of two chains, N.

To the ends of each chain N are attached the ends of two wires, 0. Theouter ends of the wires of each pair are attached to a lever, P, whichis pivoted midway between the ends of the wires to the upper end of apost, Q. The pivot-post Q can be placed at any desired distance from thegate.

With this construction, when either of the levers P is operated thecam-wheel F will be turned upon the spindle E through a part of arevolution. The first effect of the movement of the wheel F is to causeits cam to operate the lever l to draw back the latch J and release thegate, and the next effect is to swing the gate open or shut.

In the drawings the gate is shown as arranged to open only in onedirection; but it may be arranged to open in both directions, ifdesired.

' Having thus described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination, with the gate A, the latchJ, and its spring K, of the lever I, the cam-wheel F, the spring G, andan operating mechanism, substantially as herein shown and described,whereby the gate can be operated by turning the said cam-wheel, as setforth.

2. The combination, with the gate A, the latch J, and its spring K, andthe levers P, and wires 0, of the latch-lever I, the cam-wheel F, thespring G, the pulley M, and the chains N, substantially as herein shownand described, whereby the cam-wheel can be turned to open and close thegate, as set forth.
